" CAR-COUPLING..

4 SPECIFICATION forming part of Letters Patent No. 387,352, dated August 7, 1888.

Application filed September 22, i887. Serial No. 250,441.

\ To LZZ whom it may concern:

ling pins and links with two projections each one of which extends in advance of its coupling-head, the supporting-plates, which are pivoted at one end and extend through horizontal slots made through the coupling-heads, and the operating-levers connected to these supporting-plates and by which the plates are moved into any desired position, as will be more fully described hereinafter.

The object of my invention is to provide a car-coupling which is automatic in its operation and in which the pin is supported in a raised position until the cars run together, when the support is forced from under the pin and it drops through the link and couples the cars together.

Figure lis a side elevation ofa car-coupling which embodies my invention, one of the couplings having a portion of the timbers broken away, so as to show its parts in one position in solid lines and another positionin dotted lines. Fig. 2 is a plan view of the same.

Arepresents the timbers of the cars,and l 2 the draw-heads, which are secured therein in any suitable manner. The opening in each draw-head for the reception of the end ofthe link is madelargest at its outer end and tapers backward, as shown in dotted lines, toward the rear end, where the opening is `just large enough to freely admit the end of the link.

The coupling-pins P are ofthe ordinary construction, and couple with the link in the usual manner.

Secured to the timbers A of each car is a projection, D, which extends a suitable distance in advance of its couplinghead, and which projection has its front end reduced in width, so as to freely enter the space between (No model.)

the outer timbers of the opposite car and the draw-head which is secured therein, as shown in Fig. 2. Pivoted in each one of these projections D and extending horizontally through a suitable slot or opening which is made through the draw-head is a supporting-plate, E, which has an opening made through its outer end, where it projects beyond the side of the coupling, and in which opening the lower end of the lever L, pivoted upon the side of Ythe draw-head, catches. By means ot' this lever L the supporting-plate E can be moved back and forth so as to catch under the raised pin and support it in an elevated position, as shown in dotted lines in Fig. 1, or it can be moved backward, so as not to interfere with the pin in any respect. Vhen the pin P is raised upward and the upper end of the lever L is forced backward,the free end of the plate E is moved forward and its central portion catches under the lower part of the pin and supports the pin in a raised position ready for coupling.

When the cars run back, the projection D upon the Opposite car strikes against the free end of the supporting-plate E and forces it backward, so that the plate E is moved from under the pin and the pin drops through the link F, as shown.

By this construction the draw-heads can be set so as to automatically couple when they run together, or the pins can be left so as not to couple, as may be desired.

' Having thus described my invention, I elaim- 4 The combination of the draw-heads having horizontal slots made through them, the eX- tensions D, having their front ends projecting beyond the draw-heads, the pivoted supports extending through the slots in the draw-heads, the operating-levers pivoted on the drawheads, the pins, and the link, substantially asv shown and described.
